The display panel displays a sequence of screens that convey information to the operator and permit the operator to select operational modes and to input data to define the control parameters for the various operational modes. The display panel is touch sensitive, so data entry is made by the operator touching the panel at various loions defined by the various screens. The display panel and its method of inputting and displaying data are for use with an excavator machine control system that measures the angles between the machine base, boom, stick, and bucket, and that controls the hydraulic cylinders to guide the excavator bucket to dig to a desired contour.
